XE_RTP_ACTIO...ELD_SET_FUNC(9)

📦 version 7.3.1, in nixpkgs unstable

💅 XE_RTP_ACTION_FIELD_SET_FUNC 💅

okay bestie, welcome to the Kernel API Manual ✨ — this one's a macro page, and honestly she's lowkey iconic once you get what she does. Sit down, hydrate, let's go 🫶

🎀 NAME 🎀

XE_RTP_ACTION_FIELD_SET_FUNC — sets a bit range to the value that a function hands back. Literally it's giving "field set, but the value comes from a function" 💖

✨ SYNOPSIS ✨

XE_RTP_ACTION_FIELD_SET_FUNC (reg_ , mask_bits_ , func_ , ... );

periodt, that's the whole call signature 🌸

🦋 ARGUMENTS 🦋

  • reg_ — the register. the actual register, no cap 🎀
  • mask_bits_ — the mask of the bits you're changing inside that register, and together those bits form a field 💅
  • func_ — the function that returns the value you want to set in the field that mask_bits_ denotes. she's the main character here 👑
  • ... — extra fields you wanna override in the struct xe_rtp_action entry. sprinkle as needed 🙈

🌈 DESCRIPTION 🌈

so this macro works exactly like XE_RTP_ACTION_FIELD_SET — same energy — except the field value gets evaluated at the time the RTP table is processed ⭐

and like, the important bit: func_ will only be called a single time, when the RTP table is being processed 💀 once. that's it. after processing, the value in the reg_sr entry is fixed and will not be re-evaluated. so don't be out here expecting her to refresh herself, because she will not 🧚

fr fr: one call, one time, then the value is locked in forever. plan accordingly bestie 💜
